/* rf_archs.h -- defines for which architectures you want to
* include is some particular build of raidframe. Unfortunately,
* it's difficult to exclude declustering, P+Q, and distributed
* sparing because the code is intermixed with RAID5 code. This
* should be fixed.
*
* this is really intended only for use in the kernel, where I
* am worried about the size of the object module. At user level and
* in the simulator, I don't really care that much, so all the
* architectures can be compiled together. Note that by itself, turning
* off these defines does not affect the size of the executable; you
* have to edit the makefile for that.
*
* comment out any line below to eliminate that architecture.
* the list below includes all the modules that can be compiled
* out.
